发帖数: 59 | 1 Moderna said that its vaccine will be shipped at minus 4 degrees Fahrenheit
and can be kept at refrigerator temperatures for up to seven days at the
administration site. Pfizer's vaccine, though, must be maintained at minus
94 degrees during shipment and long-term storage, and must be used within 24
hours of thawing.
Pfizer's shipping requirements can be met using special containers that use
dry ice and that can keep the liquid cold for up to 10 days if unopened. But
the requirement to use the vaccine within a day unless the packaging is
kept cold with replenished dry ice has the CDC planning for the scenario in
which it would only be shippable to administration sites that have larger
patient volumes.
Supply-chain challenges for vaccine distribution, especially in rural and in
underdeveloped areas of the world, may put mRNA vaccines at a disadvantage
to competitors, a possibility investors seem have considered in the last few
days. |
